Like it or not, retailers, airports, and other businesses are increasingly tracking people's faces and mobile devices as they
walk through their premises, to better organize store layouts and provide tailored advertising.
Wi-Fi and Bluetooth signals emanating from smartphones and tablets make it possible to secretly monitor where individuals go, particularly if their location can be tracked across different networks.
If people don't religiously turn off their Wi-Fi and Bluetooth as they wander around and if their location data can be cross-referenced with store loyalty programs, it's possible to build very detailed pictures of individuals without them being aware.
Just a friendly reminder to TURN OFF your WI-FI and Bluetooth when shopping.
